Application filed December 24, 1926. Serial No. 156,834.

This invention relates to window constructions and particularlyto window con: structionshavinga drop sasl1,-that is, a

. sash that lowers downwardly.intothewindow frame below the sillinsteadnofraising upwardly. It has for its object'aparticularly simple Eandnefiicient means :by which the position of. that. portion -ofthe sash locking means which is carried by the frame is adjustable to receive the lock or boltof the sash holder on the sash when .the sash is closed with aweather strip along the lower edge thereof snugly against the sill,

. that is, thelower side of the sill. -.The.in-

vention further includes a particularly simple and efiicient means for supporting the weather strip along the lower rail of the sill.

The invention consists in'the. noval features and in the combinations and, constructions hereinafter set forth and claimed.

In describing this inventiomreference is had to the accompanying drawings in which like characters designate corresponding parts in-all the views.

Figure l is a fragmentary'faoe view of a window sash embodying my invention.

Figure 2 is a vertical sectional View.

Figures 3 and 4 are elevations, taken at a right angle to each other. of the rack formin part of the sash holdingmechanism.'

.Figure 5 is a cross sectional view of the rack. I

Figure '6 is an enlarged detail View of the adjustable portion of the 'rack.

This invention comprises a window frame, a drop sash movable in the frameand having a weather strip along its lower rail for engaging the innerface of the sill of the frame when the sash is elevated or closed. sash holding means including a rack carried by the frame and a sash lock carried by the sash and having a movable member coacting with the rack, the rack including an adjustable section or a separable section having means as a tooth or indentation for coacting with the look when the sash is in closed position with the weather strip tightly against the sill.

l designates the frame. 2 is the sash movable in the frame, the frame having a recess or well below its sill 3. The sash maybe of any. suitable form, size and construction, that here shown being formed up out of sheet metal and the lower rail 4 thereof'is formed with a wood filler 4-.

-15 is. the weather strip along the lower edge of therailAand arranged to engage the inner side of the sill3 when the sash is :w

closedw.

.is-the rack suitably arranged along the sides of the frame and? designates the sash lock-located on the sash at theupper corner thereof, -ethere being one at each upper corner.

.T his sash holder includes a movable bolt member 8 which coacts with the rack 6 and which is operated by a thumb lever 9 arrangedjnfjuxtapositionto a stationary pinch handle 10on the casing of-the sash holder. Tillie. sash holder itselfmay be of any suitable form, size and construction.

11 .is the separable or adjustable upper end .section of the rack 6, this adjustable sectionhaving a tooth or notch 12 for receiving the bolt 8 when the sash is closed. Inorder that this notch or tooth 12 may be readily located so that it receives the bolt 8 when the sash is closed with the weather strip 5 against the under side of the sill 3, the section 11 is separable so as to be so properly located and after it is properly located, the remainder of the rack 6 is placed in position. The adjustable portion H is preferably a castinghaving a stem 13 which telescopes into the upper end of the rack 6 which is in the form of a channel in cross section, the. outer faces of the casing llbeing flush with the outer faces of the rackv 6 when the parts are assembled. The rack .6 and its adjustable portion or casing 11 are secured to the frame in any suitable manner as by screws 14.

Obviously, it is essential that the weather strip be tight against the inner face of the sash 3 when the window is closed and that when the sash is closed, the rack or the portion 11 thereof must be at the proper height to coact with the bolt 8 so that the bolt will hold the sash with the weather strip 5 against the sill 3.

By this construction, the section 11 can be readily located in osition to coact with the bolt8 when the strip 5 is against the sill 3 and that after this section 11 is secured at the proper height, the remainder or major portion of the rack 6 can then be placed in position with the stem 13 fitting in the end of the channel of the rack 6.

The weather strip 5 includes a buffer portion of rubber or any ethersuitable .inaterial held ,in in' upwardl enamel 15 secured along the'lower edge at the rail 4 and out of the plane-oftherail so as to engage the inner face of the sill 3. The channel 1:3 is here shown as iforined up :of sheet metal and with a laterally extending flange it lapping the lower etlge of the rail 4and secured thereto in any-suitable manner as by screws 17.
